ABSTRACT

A method including communicating, by a first device in communication with a second device in a mesh network, meshnet data with the second device based at least in part on utilizing a meshnet local port dedicated for communicating the meshnet data; and transmitting, by the first device to a control infrastructure device, a binding request based at least in part on utilizing the meshnet local port, the binding request requesting the control infrastructure to determine a currently allocated public port associated with the first device. Various other aspects are contemplated.

FIELD OF DISCLOSURE

Aspects of the present disclosure generally relate to communications in networks, and more particularly to efficient routing of communications in a mesh network.

BACKGROUND

Users may rely on mesh networks (also referred to as “meshnets”) to communicate (e.g., transmit and/or receive) data among a plurality of endpoints (e.g., user devices) via one or more Internet nodes (e.g., bridges, switches, infrastructure devices, etc.). In an example, a mesh network may include a plurality of endpoints communicatively coupled to each other directly or via the one or more Internet nodes. A mesh network in which all endpoints are communicatively coupled to each other may be referred to as a fully connected network. Data transmitted by a first endpoint, from among the plurality of endpoints, may be routed over the Internet via the one or more Internet nodes to a second endpoint from among the plurality of endpoints. Also, data transmitted by the first endpoint may be routed to two or more endpoints from among the plurality of endpoints.

In a mesh network, the plurality of endpoints may cooperate with each other to enable communication of the data among the plurality of endpoints. In an example, one or more of the endpoints may participate in communication of the data. In this way, the mesh network may avoid relying on a given endpoint for communication of the data. Some mesh networks may have the ability to dynamically self-organize and self-configure the plurality of endpoints. This ability may allow such mesh networks to enable dynamic distribution of workloads, particularly in the event that one or more endpoints should fail. Further, installation overhead may be reduced.

SUMMARY

In one aspect, the present disclosure contemplates a method including communicating, by a first device in communication with a second device in a mesh network, meshnet data with the second device based at least in part on utilizing a meshnet local port dedicated for communicating the meshnet data; and transmitting, by the first device to a control infrastructure device, a binding request based at least in part on utilizing the meshnet local port, the binding request requesting the control infrastructure to determine a currently allocated public port associated with the first device.

In another aspect, the present disclosure contemplates a first device including a memory and a processor configured to: communicate, while in communication with a second device in a mesh network, meshnet data with the second device based at least in part on utilizing a meshnet local port dedicated for communicating the meshnet data; and transmit, to a control infrastructure device, a binding request based at least in part on utilizing the meshnet local port, the binding request requesting the control infrastructure to determine a currently allocated public port associated with the first device.

In another aspect, the present disclosure contemplates a non-transitory computer readable medium storing instructions, which when executed by a processor associated with a first device, cause the processor to: communicate, while in communication with a second device in a mesh network, meshnet data with the second device based at least in part on utilizing a meshnet local port dedicated for communicating the meshnet data; and transmit, to a control infrastructure device, a binding request based at least in part on utilizing the meshnet local port, the binding request requesting the control infrastructure to determine a currently allocated public port associated with the first device.

FIG. 1 is an illustration of an example 100 associated with efficient routing of communications in a mesh network, according to various aspects of the present disclosure. Example 100 shows an architectural depiction of included components. In some aspects, the components may include one or more user devices 102 capable of communicating with a mesh network service provider (MSP) control infrastructure 104 for purposes of obtaining mesh network services. In some aspects, the one or more user devices 102 may communicate with the MSP control infrastructure 104 over a network 118. The MSP control infrastructure 104 may be controlled by a mesh network service provider and may include an application programming interface (API) 106, a user database 108, processing unit 110, and a meshnet database 112. In some aspects, a user device 102 may utilize a processing unit 116 and/or a client application 114, which is provided by the MSP control infrastructure 104, to communicate with the API 106. The API 106 may be capable of communicating with the user database 108 and with the processing unit 110. Additionally, the processing unit 110 may be capable of communicating with the meshnet database 112, which may be capable of storing data associated with providing mesh network services.

The user device 102 may be a physical computing device capable of hosting the client application 114 and of connecting to the network 118. The user device 102 may be, for example, a laptop, a mobile phone, a tablet computer, a desktop computer, a smart device, a router, or the like. In some aspects, the user device 102 may include, for example, mesh network enabled Internet-of-Things (IoT) devices such as smart home appliances, smart home security systems, autonomous vehicles, smart health monitors, smart factory equipment, wireless inventory trackers, biometric cyber security scanners, or the like. The network 118 may be any digital telecommunication network that permits several nodes to share and access resources. In some aspects, the network 118 may include one or more of, for example, a local-area network (LAN), a wide-area network (WAN), a campus-area network (CAN), a metropolitan-area network (MAN), a home-area network (HAN), Internet, Intranet, Extranet, and Internetwork.

The MSP control infrastructure 104 may include a combination of hardware and software components that enable provision of mesh network services to the user device 102. The MSP control infrastructure 104 may interface with (the client application on) the user device 102 via the API 106, which may include one or more endpoints to a defined request-response message system. In some aspects, the API 106 may be configured to receive, via the network 118, a connection request from the user device 102 to establish a connection with the MSP control infrastructure 104 for purposes of obtaining the mesh network services. The connection request may include an authentication request to authenticate the user device 102. The API 106 may receive the authentication request and a request for the mesh network services in a single connection request. In some aspects, the API 106 may receive the authentication request and the request for the mesh network services in separate connection requests.

The API 106 may further be configured to handle the connection request by mediating the authentication request. For instance, the API 106 may receive from the user device 102 credentials including, for example, a unique combination of a user ID and password for purposes of authenticating the user device 102. In another example, the credentials may include a unique validation code known to an authentic user. The API 106 may provide the received credentials to the user database 108 for verification.

The user database 108 may include a structured repository of valid credentials belonging to authentic users. In one example, the structured repository may include one or more tables containing valid unique combinations of user IDs and passwords belonging to authentic users. In another example, the structured repository may include one or more tables containing valid unique validation codes associated with authentic users. The mesh network service provider may add, delete, or modify such valid unique combinations of user IDs and passwords from the structured repository at any time. Based at least in part on receiving the credentials from the API 106, the user database 108 and a processor (e.g., the processing unit 110 or another local or remote processor) may verify the received credentials by matching the received credentials with the valid credentials stored in the structured repository. In some aspects, the user database 108 and the processor may authenticate the user device 102 when the received credentials match at least one of the valid credentials. In this case, the mesh network service provider may provide mesh network services to the user device 102. When the received credentials fail to match at least one of the valid credentials, the user database 108 and the processor may fail to authenticate the user device 102. In this case, the mesh network service provider may decline to provide mesh network services to the user device 102.

When the user device 102 is authenticated, the user device 102 may initiate a connection and may transmit to the API 106 a request for the mesh network services. The processing unit 110 included in the MSP control infrastructure 104 may be configured to determine a mesh network associated with the user device 102 and/or to identify one or more user devices to be included within the determined mesh network. The processing unit 110 may utilize the API 106 to transmit information associated with the mesh network and/or the identified one or more user devices to the user device 102. The user device 102 may transmit an initiation request to establish secure connections (e.g., encrypted tunnels) with the one or more user devices. In some aspects, the one or more user devices with which the user device 102 establishes the secure connections may also host respective client applications for communicating with the MSP control infrastructure 104 and/or with the user device 102. In some aspects, the processing unit 110 may be a logical unit including a logical component configured to perform complex operations associated with computing, for example, numerical weights related to various factors associated with providing the meshnet services.

One or more components (e.g., API 106, user database 108, processing unit 110, and/or meshnet database 112, processing unit 116) included in the MSP control infrastructure 104 and/or included in the user device 102 may further be associated with a controller/processor, a memory, a communication interface, or a combination thereof (e.g., FIG. 8 ). For instance, the one or more components of the set of components may include or may be included in a controller/processor, a memory, or a combination thereof. In some aspects, the one or more of the components included in the MSP control infrastructure 104 and/or the user device 102 may be separate and distinct from each other. Alternatively, in some aspects, one or more of the components included in the MSP control infrastructure 104 and/or the user device 102 may be combined with one or more of other components included in the MSP control infrastructure 104. In some aspects, the one or more of the components included in the MSP control infrastructure 104 and/or the user device 102 may be local with respect to each other. Alternatively, in some aspects, one or more of the components included in the MSP control infrastructure 104 and/or the user device 102 may be located remotely with respect to one or more of other components included in the MSP control infrastructure 104 and/or the user device 102. Additionally, or alternatively, one or more components of the components included in the MSP control infrastructure 104 and/or the user device 102 may be implemented at least in part as software stored in a memory. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or a processor to perform the functions or operations of the component. Additionally, or alternatively, a set of (one or more) components shown in FIG. 1 may be configured to perform one or more functions described as being performed by another set of components shown in FIG. 1 .

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

Endpoints (e.g., user devices) may rely on a mesh network to communicate (e.g., transmit and/or receive) meshnet data among the endpoints. In example 200 shown in FIG. 2 , the endpoints may include a first user device, a second user device, a third user device, and/or a fourth user device. The meshnet data may be communicated using wired communications and/or wireless communications over a network such as, for example, the Internet. The meshnet data may include any information including digital information such as, for example, documents including data, voice data, image data, signal data, and/or video data. Further, the internal mesh network may be a secure mesh network that may enable the endpoints to communicate the meshnet data in encrypted form via meshnet connections (shown as double-ended arrows in FIG. 2 ).

Each endpoint may be associated with a respective local area network (LAN) and may utilize a respective local port to communicate the meshnet data. In turn, the respective LAN may be associated with a respective network address translation (NAT) device for conducting NAT procedures, including mapping the respective local port with a respective public port (e.g., UDP port, TCP port, etc.). The NAT device may route the meshnet data transmitted by the respective local port to the respective public port and then to another endpoint in the mesh network. Similarly, the NAT device may receive meshnet data transmitted by another endpoint at the respective public port and may route the received meshnet data to the respective local port.

Further, the respective local port may be dedicated for communicating meshnet data. As a result, an operating system associated with a user device may expect to utilize the dedicated respective local port for communicating meshnet data. In other words, the operating system associated with the user device may expect to utilize the dedicated respective local port for transmitting meshnet data to one or more endpoints in the mesh network and for receiving meshnet data from the one or more endpoints in the mesh network.

FIG. 3 shows example 300 depicting a LAN associated with, for example, the first user device. As shown in example 300, the first user device may utilize a dedicated respective local port (e.g., Meshnet Local Port) to communicate meshnet data with one or more endpoints in the mesh network. The first user device may also include one or more other local ports (e.g., Another Local Port) for communicating data other than the meshnet data. In this case, when the first user device transmits meshnet data to the one or more endpoints, the first user device may utilize the meshnet local port to transmit the meshnet data. The NAT device may receive the transmitted meshnet data, may map the meshnet local port to a currently allocated public port (e.g., first public port), and may utilize the first public port to transmit the meshnet data to the one or more endpoints. Similarly, when the first user device receives meshnet data from the one or more endpoints, the NAT device may utilize the first public port to receive the meshnet data, and based at least in part on the mapping of the meshnet local port to the first public port, may route the received meshnet data to the meshnet local port of the first user device.

In some cases, while conducting the NAT procedures, the NAT device may reallocate the first public port for tasks other than routing the meshnet data and may allocate a second public port for routing the meshnet data. In an example, such reallocation may be due to lack of communication in the mesh network by the first user device for a threshold amount of time, or for a need that the first public port supports a task other than routing the meshnet data, or the like. Because the first user device and other endpoints in the mesh network are unaware of the reallocation of the first public port, the endpoints may continue to communicate the meshnet data to the first public port. The NAT device may drop and/or discard such communicated meshnet data. As a result, the first user device may fail to receive the communicated meshnet data.

To keep the first user device and other endpoints informed of reallocation of public ports by the NAT device, the first user device may transmit a binding request to a MSP control infrastructure. Based at least in part on receiving the binding request, the MSP control infrastructure may determine a currently allocated public port (e.g., second public port) for routing the meshnet data to and from the first user device, and may transmit, to all endpoints in the mesh network, communication information including information indicating that the second public port is the currently allocated public port. As a result, to continue to communicate with the first user device, the endpoints in the mesh network may transmit meshnet data to the second public port.

Because the meshnet local port is dedicated for communicating meshnet data, the first user device may utilize another local port to transmit the binding request. The NAT device may receive the binding request at the currently allocated public port (the first public port or the second public port) and may route the binding request to the MSP control infrastructure. Based at least in part on receiving the binding request, the MSP control infrastructure may determine the currently allocated public port for communicating meshnet data and may transmit a response including the communication information to the currently allocated public port. The NAT device may route the response back to the other local port from which the binding request was received.

Because the binding request was transmitted utilizing the other local port and/or because the response from the MSP control infrastructure was routed to the other local port, the NAT device may start routing all meshnet data communicated with respect to the first user device to the other local port. In an example, the NAT device may route meshnet data received from the one or more endpoints to the other local port. The operating system associated with the first user device may drop and/or discard such meshnet data received at the other local port because the operating system expects to receive meshnet data at the meshnet local port dedicated for communicating meshnet data.

As a result, the first user device may fail to receive the communicated meshnet data, and communication among the endpoints may be interrupted. Further, the other endpoints may retransmit the communications to the first user device to ensure receipt thereof by the first user device. Such transmission and retransmission of communications may inefficiently consume user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and the network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) that can otherwise be utilized to perform suitable tasks associated with the mesh network. The above discussion with respect to the first user device may also apply to the one or more endpoints in the mesh network.

Various aspects of systems and techniques discussed in the present disclosure enable efficient routing of communications in a mesh network. In some aspects, an MSP control infrastructure may provide the mesh network to enable the endpoints to securely communicate meshnet data. Further, the MSP control infrastructure may provide the endpoints with respective client applications to communicate with the MSP control infrastructure, to communicate with each other for setting up respective meshnet connections to be utilized for communicating the data in the mesh network, and/or to communicate meshnet data (e.g., meshnet communications) with each other over the respective meshnet connections in the mesh network. The MSP control infrastructure and the respective client applications may enable efficient routing of communications in a mesh network. In some aspects, the respective client applications may be configured to establish a support meshnet connection with the MSP control infrastructure, thereby enabling the endpoints to communicate with the MSP control infrastructure as if the MSP control infrastructure were an endpoint in the mesh network. As a result, the respective client applications may be enabled to utilize respective local ports, that are dedicated for communicating meshnet data, to communicate with the MSP control infrastructure. In some aspects, the respective client applications may utilize respective local ports to communicate binding requests and associated responses between the MSP control infrastructure and the respective client applications. As a result, NAT devices associated with the endpoints may route the meshnet data to the respective local ports, as expected by respective operating systems associated with the endpoints. In this way, the endpoints may avoid dropping and/or discarding of meshnet data, and communication among the endpoints may continue uninterrupted. Further, instances of inefficient transmissions and retransmissions of communications among the endpoints may be mitigated. As a result, the MSP control infrastructure and the respective client applications may enable efficient utilization of user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) for performing suitable tasks associated with the secure mesh network.

In some aspects, a processor (e.g., processing unit 116, processor 820) associated with a user device may communicate, while in communication with a second device in a mesh network, meshnet data with the second device based at least in part on utilizing a meshnet local port dedicated for communicating the meshnet data; and transmit, to a control infrastructure device, a binding request based at least in part on utilizing the meshnet local port, the binding request requesting the control infrastructure to determine a currently allocated public port associated with the first device.

As indicated above, FIGS. 2 and 3 are provided as examples. Other examples may differ from what is described with regard to FIGS. 2 and 3 .

FIG. 4 is an illustration of an example flow 400 associated with efficient routing of communications in a mesh network, according to various aspects of the present disclosure. The example flow 400 may include a first user device (e.g., first endpoint), MSP control infrastructure 104, and a second user device (e.g., second endpoint) in communication with each other. The first user device and the second user device may be similar to a user device 102 discussed above with respect to FIG. 1 . In some aspects, the first user device and the second user device may be associated with a single account registered with the MSP control infrastructure 104. In some aspects, the first user device and the second user device may be associated with different accounts registered with the MSP control infrastructure 104. In some aspects, the first user device and the second user device may be located locally (e.g., in the same room, in the same building, etc.). In some aspects, the first user device and the second user device may be located remotely (e.g., in different buildings, in different cities, in different states, in different countries, etc.) with respect to each other.

The first user device may install a first client application (e.g., client application 104) and the second user device may install a second client application (e.g., client application 104), the first client application and the second client application being associated with (e.g., provided by) the MSP control infrastructure 104. The first user device and the second user device may use the respective client applications to communicate with an application programming interface (API) and/or a processor (e.g., processing unit 110, processor 820) associated with the MSP control infrastructure 104. In some aspects, the first user device, the MSP control infrastructure 104, and the second user device may communicate with each other over a network (e.g., network 118). As discussed elsewhere herein, the MSP control infrastructure 104 may enable the first user device and/or the second user device to obtain the mesh network services.

Although only two user devices (e.g., endpoints) are shown in FIG. 4 , the present disclosure contemplates the mesh network to include any number of user devices that perform the processes discussed herein in a similar and/or analogous manner. For instance, the mesh network may include a third user device and a fourth user device, as discussed above with respect to FIG. 2 , that perform the processes discussed herein in a similar and/or analogous manner. Further, user devices may leave or join the mesh network in an ad-hoc manner.

In some aspects, the client applications may enable the user devices to receive information to be processed by the client applications and/or by the MSP control infrastructure 104. Each of the client applications may include respective graphical user interfaces to receive the information via local input interfaces (e.g., touch screen, keyboard, mouse, pointer, etc.) associated with the user devices. The information may be received via text input or via a selection from among a plurality of options (e.g., pull down menu, etc.). In some aspects, the first client application and/or the second client application may activate and/or enable, at a time associated with the registration (e.g., after the registration), the graphical interface for receiving the information. For instance, the first client application (or the second client application) may cause a screen (e.g., local screen) associated with the first user device (or the second user device) to display, for example, a pop-up message to request entry of the information. Further, the client applications may enable transmission of at least a portion of the information to the MSP control infrastructure 104. In some aspects, the first client application may utilize a first processing unit (e.g., processing unit 116, processor 820) associated with the first user device to perform processes/operations associated with obtaining the mesh network services and the second application may utilize a second processing unit (e.g., processing unit 116, processor 820) associated with the second user device to perform processes/operations associated with obtaining the mesh network services.

As shown by reference numeral 405, the first user device may register an account with the MSP control infrastructure 104. In some aspects, during the registration, the first user device may provide registration information such as, for example, identity of an owner of the first user device, a phone number associated with the first user device, an email address associated with the first user device, or the like. In some aspects, the first user device may set up an access system including login information (e.g., access information) such as, for example, username, password, or the like to subsequently gain access to the registered account. In some aspects, the first user device may share the login information with other user devices (e.g., second user device) associated with the first user device to enable the other user devices to utilize the login information to gain access to the MSP control infrastructure 104 via the registered account. In some aspects, a given user device may be associated with the first user device because the given user device may be available to a user/owner of the first user device. In some aspects, when the second user device is not associated with the registered account associated with the first user device, the second user device may register a different account with the MSP control infrastructure 104.

In some aspects, the first user device and the second user device may utilize the login information to access the registered account/accounts to communicate with the MSP control infrastructure 104. As shown by reference numeral 310, based at least in part on the first user device and the second user device accessing the registered account/accounts to communicate with the MSP control infrastructure 104, the MSP control infrastructure 104 may transmit, and the first client application and the second client application may receive, MSP access information. In some aspects, the MSP access information may include UDP access information. The UDP access information may include information regarding an infrastructure UDP IP address and an infrastructure UDP port associated with the MSP control infrastructure 104. The MSP control infrastructure 104 may utilize the infrastructure UDP IP address and the infrastructure UDP port to communicate utilizing the UDP. In some aspects, the first user device and the second user device may utilize the infrastructure UDP IP address and the infrastructure UDP port to communicate with the MSP control infrastructure 104 regarding the mesh network. Further, the first client application and the second client application may obtain from, for example, a domain name services (DNS) server, transmission control protocol (TCP) access information associated with the MSP control infrastructure 104. Such TCP access information may include information regarding an infrastructure TCP IP address and an infrastructure TCP port associated with the MSP control infrastructure 104. The MSP control infrastructure 104 may utilize the infrastructure TCP IP address and the infrastructure TCP port to communicate utilizing the TCP.

As shown by reference numeral 415, the first client application and the second client application may determine information based at least in part on the registration of the account/accounts with the MSP Control Infrastructure 104. In an example, the first client application may determine an asymmetric first assigned key pair associated with the first user device. The first assigned key pair may be unique to the first user device and may include a first assigned public key and a first assigned private key. In this way, the first assigned public key and the first assigned private key may be device-specific and maybe associated with the registered account. In some aspects, the first assigned public key and the first assigned private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the first assigned public key may be decrypted by utilizing the first assigned private key.

Similarly, the second client application may determine an asymmetric second assigned key pair associated with the second user device. The second assigned key pair may be unique to the second user device and may include a second assigned public key and a second assigned private key. In this way, the second assigned public key and the second assigned private key may be device-specific and maybe associated with the registered account. In some aspects, the second assigned public key and the second assigned private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the second assigned public key may be decrypted by utilizing the second assigned private key.

As shown by reference numeral 420, the client applications may transmit, and the MSP control infrastructure 104 may receive, at least a portion of the information determined by the client applications. For instance, the first client application may transmit, for example, the first assigned public key to the MSP control infrastructure 104 and the second client application may transmit, for example, the second assigned public key to the MSP control infrastructure 104. The MSP control infrastructure 104 may store and correlate the received information in association with the registered account and/or with the respective user devices. In an example, the MSP control infrastructure 104 may store and correlate the first assigned public key in association with the registered account and the first user device, and may store and correlate the second assigned public key in association with the registered account and the second user device. In some aspects, the first client application and the second client application may utilize the infrastructure TCP IP address and the infrastructure TCP port to transmit the first assigned public key and the second assigned public key to the MSP control infrastructure 104 via the TCP.

Further, as shown by reference numeral 425, the MSP control infrastructure 104 may determine that the first user device and the second user device are to be included in the same mesh network. In some aspects, when the first user device and the second user device are associated with the same registered account, the MSP control infrastructure 104 may make such a determination regarding the secure mesh network based at least in part on determining that the first user device and the second user device are communicating with the MSP control infrastructure 104 by utilizing the login information associated with the same registered account. In some aspects, when the first user device and the second user device are associated with different registered accounts, the MSP control infrastructure 104 may make such a determination regarding the secure mesh network based at least in part on the first user device (and/or the second user device) providing information indicating that the first user device and the second user device are to be included in the same mesh network. Such information may include, for example, identification information (e.g., type of device, user name, email address, etc.) associated with the second user device (or the first user device), the second IP address (or the first IP address), or the like.

Based at least in part on determining that the first user device and the second user device are to be included in the same mesh network, as shown by reference numeral 330, the MSP control infrastructure 104 may determine meshnet IP addresses for the first user device and for the second user device. In an example, the MSP control infrastructure 104 may determine a first meshnet IP address associated with the first user device and a second meshnet IP address associated with the second user device. The first client application and/or another application installed on the first user device and/or the operating system associated with the first user device may utilize the first meshnet IP address and/or the first local meshnet port to communicate data with the endpoints over meshnet connections in the mesh network and the second user device may utilize the second meshnet IP address and/or the second local meshnet port to communicate data with the endpoints over the meshnet connections in the mesh network. In an example, with respect to communication between the first user device and the second user device, the first user device may determine a first meshnet IP packet indicating the first meshnet IP address as a source address, the first local meshnet port as a source port, the second meshnet IP address as a destination address, and the second local meshnet port as a destination port. The first user device may encrypt and encapsulate the first meshnet IP packet within a payload of a transmitted UDP IP packet. The second user device may receive the UDP IP packet, may decrypt the first meshnet IP packet, and may route the first meshnet IP packet to the second local meshnet port. Similarly, the second user device may determine a second meshnet IP packet indicating the second meshnet IP address as a source address, the second local meshnet port as a source port, the first meshnet IP address as a destination address, and the first local meshnet port as a destination port. The second user device may encrypt and encapsulate the second meshnet IP packet within a payload of a transmitted UDP IP packet. The first user device may receive the UDP IP packet, may decrypt the first meshnet IP packet, and may route the second meshnet IP packet to the first local meshnet port. The MSP control infrastructure 104 may determine the first meshnet IP address and the second meshnet IP address from, for example, a pool of reserved IP addresses included in a subnet associated with an internal network of the ISP.

As shown by reference numeral 435, the first user device and the second user device may transmit, and the MSP control infrastructure 104 may receive, respective binding requests. In some aspects, the first user device may transmit the first binding request to the MSP control infrastructure 104 using the UDP by utilizing the UDP access information received from the MSP control infrastructure 104 (e.g., block 420). In this case, the first user device may transmit a first binding request to the MSP control infrastructure 104 to request the MSP control infrastructure 104 to determine a first public UDP IP address (e.g., communication address) and/or a first public UDP port (e.g., communication port) associated with the first user device. As discussed below in further detail, the first public UDP IP address and/or the first public UDP port are to be utilized by the second user device to communicate with the first user device in the mesh network. Similarly, the second user device may transmit the second binding request to the MSP control infrastructure 104 using the UDP by utilizing the UDP access information received from the MSP control infrastructure 104 (e.g., block 420). In this case, the second user device may transmit a second binding request to the MSP control infrastructure 104 to request the MSP control infrastructure 104 to determine a second public UDP IP address (e.g., communication address) and/or a second public UDP port (e.g., communication port) associated with the second user device. As discussed below in further detail, the second UDP IP address and/or the second UDP port are to be utilized by the first user device to communicate with the second user device in the mesh network.

In some aspects, the first public UDP IP address and/or the first public UDP port may be determined by a first NAT device responsible for managing operation of the first user device in a first local network. In an example, the first NAT device may translate a first local UDP IP address and/or a first local UDP port associated with the first user device to the first public UDP IP address and/or the first public UDP port that the first user device utilizes to communicate (e.g., transmit and/or receive) over the Internet using the UDP. Similarly, the second public UDP IP address and/or the second public UDP port may be determined by a second NAT device responsible for managing operation of the second user device in a second local network. In an example, the second NAT device may translate a second local UDP IP address and/or a second local UDP port associated with the second user device to the second public UDP IP address and/or the second public UDP port that the second user device utilized to communicate (e.g., transmit and/or receive) over the Internet using the UDP.

Based at least in part on receiving the respective binding requests, as shown by reference numeral 440, the MSP control infrastructure 104 may determine public UDP IP addresses and/or public UDP ports associated with the first user device and the second user device. In an example, based at least in part on receiving the first binding request, the MSP control infrastructure 104 may determine the first public UDP IP address and/or the first public UDP port associated with the first user device. In some aspects, the MSP control infrastructure 104 may determine the first public UDP IP address and/or the first public UDP port based at least in part on analyzing the UDP communication (e.g., UDP IP packet) including the first binding request received from the first user device. The UDP communication may include, for example, a header that indicates the first public UDP IP address as a source UDP IP address and/or the first public UDP port as a source UDP port associated with the first user device. Further, the MSP control infrastructure 104 may store and correlate the first public UDP IP address and/or the first UDP port in association with the first user device in, for example, the meshnet database 112. Similarly, based at least in part on receiving the second binding request, the MSP control infrastructure 104 may determine the second public UDP IP address and/or the second public UDP port associated with the second user device. In some aspects, the MSP control infrastructure 104 may determine the second public UDP IP address and/or the second public UDP port based at least in part on analyzing the UDP communication (e.g., UDP IP packet) including the second binding request received from the second user device. The UDP communication may include, for example, a header that indicates the second public UDP IP address as a source UDP IP address and/or the second public UDP port as a source UDP port associated with the second user device. Further, the MSP control infrastructure 104 may store and correlate the second public UDP IP address and/or the second public UDP port in association with the second user device in, for example, the meshnet database 112.

Based at least in part on determining the public UDP IP addresses and/or the public UDP ports, as shown by reference numeral 445, the MSP control infrastructure 104 may transmit, and the first client application and the second client application may receive, communication information. In an example, the MSP control infrastructure 104 may transmit, and the first client application may receive, first communication information including the first meshnet IP address associated with the first user device, the second meshnet IP address associated with the second user device, the second public UDP IP address and/or the second public UDP port associated with the second user device, and the second public key associated with the second user device. Similarly, the MSP control infrastructure 104 may transmit, and the second client application may receive, second communication information including the first public UDP IP address and/or the first public UDP port associated with the first user device, the first public key associated with the first user device, the first meshnet IP address associated with the first user device, and the second meshnet IP address associated with the second user device. As discussed below in further detail, the above transmission of communication information may enable the first user device and the second user device to communicate securely and privately in the mesh network.

As shown by reference numeral 450, the first client application and the second client application may communicate with each other directly to set up a meshnet connection (e.g., an encrypted tunnel) for communicating encrypted data in the hybrid mesh network. To set up the meshnet connection, the first client application may utilize the second assigned public key and/or the second public IP address (e.g., second UDP IP address) to securely (e.g., in encrypted form) communicate with the second client application, and the second client application may utilize the first assigned public key and/or the first public IP address (e.g., first UDP IP address) to securely communicate with the first client application. In some aspects, the first client application and the second client application may communicate to securely/privately negotiate parameters (e.g., a symmetric encryption/decryption key) associated with the meshnet connection. In some aspects, the parameters may be randomly generated to provide optimized security to the communications. In an example, the first client application and the second client application may privately negotiate a randomly generated symmetric key that is to be utilized by the first client application and the second client application for encrypting and decrypting data communicated via the meshnet connection. The randomly generated symmetric key may be determined based at least in part on any combination of the first public key, the second public key, and/or randomly generated numbers. Additionally, the first client application and the second client application may utilize a secure protocol (e.g., Wireguard, IP sec, etc.) to communicate the data via the meshnet connection.

Additionally, or alternatively, the first client application and the second client application may communicate with each other indirectly via, for example, a relay device (e.g., a relay server) to set up the meshnet connection. In an example, the first client application may provide the first assigned public key to a relay server, which may store an association of the first assigned public key with the first client application. In some aspects, the association may include an association between the first assigned public key and a first communication connection between the relay server and the first client application. Similarly, the second client application may provide the second assigned public key to the relay server, which may store an association of the second assigned public key with the second client application. In some aspects, the association may include an association between the second assigned public key and a second communication connection between the relay server and the first client application. The relay server may rely on the stored associations of public keys and client applications to determine a destination of a received message. In some aspects, the relay server may include a network of relay servers that enable the first client application and the second client application to communicate with each other. In this case, the first client application and the second client application may provide the respective assigned public keys to different relay servers included within the network of relay servers.

In some aspects, the first client application may transmit, to the relay server, a first message that is to be delivered to the second client application. Along with the first message, the first client application may transmit the second assigned public key. Further, the first client application may encrypt the first message utilizing the second assigned public key. In some aspects, the first client application may encrypt the first message based at least in part on utilizing the negotiated randomly generated symmetric key. Based at least in part on receiving the encrypted first message and the second assigned public key, the relay server may determine from stored associations that the second assigned public key is associated with the second client application. As a result, the relay server may determine that the first message is to be relayed (e.g., transmitted) to the second client application. Similarly, the second client application may transmit, to the relay server, a second message that is to be delivered to the first client application. Along with the second message, the second client application may transmit the first assigned public key. Further, the second client application may encrypt the second message utilizing the first assigned public key. In some aspects, the second client application may encrypt the second message based at least in part on utilizing the negotiated randomly generated symmetric key. Based at least in part on receiving the encrypted second message and the first assigned public key, the relay server may determine from stored associations that the first assigned public key is associated with the first client application. As a result, the relay server may determine that the second message is to be relayed (e.g., transmitted) to the first client application. In this way, the relay server may enable the first client application and the second client application to communicate with each other to set up the meshnet connection.

Based at least in part on setting up the meshnet connection, the first client application and the second client application may begin communicating encrypted data via the meshnet connection based at least in part on utilizing the negotiated parameters and the secure protocol. In a similar and/or analogous manner, the first client application may set up meshnet connections with a third client application installed in the third client application and with a fourth client application associated with the fourth client application. Also, in a similar and/or analogous manner, the second client application may set up meshnet connections with the first client application, the third client application, and the fourth client application. Further, in a similar and/or analogous manner, the third client application may set up meshnet connections with the first client application, the second client application, and the fourth client application. Finally, in a similar and/or analogous manner, the fourth client application may set up meshnet connections with the first client application, the second client application, and the third client application. Additional client applications that enter the mesh network may also set up meshnet connections with the other client applications included in the mesh network.

Further, based at least in part on setting up the meshnet connection, as shown by reference numeral 455, the first user device, the second user device, and the MSP control infrastructure 104 may enable efficient routing of communications in the mesh network. In some aspects, while communicating data with the second user device via the meshnet connection in the mesh network, the first client application may establish a first support meshnet connection with the MSP control infrastructure 104 and the second client application may establish a second support meshnet connection with the MSP control infrastructure 104.

With respect to the first user device, the first client application and the MSP control infrastructure 104 may communicate with each other to set up the first support meshnet connection (e.g., an encrypted tunnel) for communicating encrypted data. To set up the first support meshnet connection, the first client application may utilize the MSP access information (e.g., infrastructure UDP IP address and/or infrastructure UDP port) to communicate with the MSP control infrastructure 104. In some aspects, the first client application and the MSP control infrastructure 104 may communicate to negotiate parameters (e.g., a symmetric encryption/decryption key) associated with the first support meshnet connection. In some aspects, the parameters may be randomly generated to provide optimized security to the communications. In an example, the first client application and the MSP control infrastructure 104 may negotiate a randomly generated symmetric key that is to be utilized by the first client application and the MSP control infrastructure 104 for encrypting and decrypting data communicated via the first support meshnet connection. In some aspects, the first client application and the MSP control infrastructure 104 may determine the randomly generated symmetric key based at least in part on utilizing the first assigned public key and/or a randomly generated number. Additionally, the first client application and the MSP control infrastructure 104 may utilize a secure protocol (e.g., Wireguard, IP sec, etc.) to communicate the data via the first support meshnet connection. Based at least in part on setting up the first support meshnet connection, the first client application and the MSP control infrastructure 104 may communicate encrypted data via the first support meshnet connection based at least in part on utilizing the negotiated parameters and the secure protocol.

In some aspects, the first support meshnet connection between the first user device and the MSP control infrastructure 104 may be dedicated for communicating current binding requests and associated responses. In some aspects, during operation within the mesh network (e.g., while communicating with the endpoints in the mesh network), the first client application may utilize the first support meshnet connection to transmit, to the MSP control infrastructure 104, a first current binding request to request the MSP control infrastructure 104 to determine a current first public UDP IP address (e.g., currently allocated public communication address) and/or a current first public UDP port (e.g., currently allocated public communication port) associated with the first device. Because the current binding request is transmitted via the first support meshnet connection, the first client application and/or an operating system associated with the first user device may consider the current binding request as meshnet data. As a result, the first client application may utilize the dedicated meshnet local port to transmit the binding request. Based at least in part on a mapping of the dedicated meshnet local port with the current first public UDP port, the NAT device associated with the first user device may receive the binding request at the current first public UDP port and may transmit the binding request to the MSP control infrastructure 104.

Based at least in part on receiving the first current binding request, the MSP control infrastructure 104 may determine the current first public UDP IP address and/or the current first public UDP port associated with the first user device. In some aspects, the MSP control infrastructure 104 may determine the current first public UDP IP address and/or the current first public UDP port based at least in part on analyzing the UDP communication (e.g., UDP IP packet) including the first current binding request received from the first user device. The UDP communication may include, for example, a header that indicates the current first public UDP IP address as a source UDP IP address and/or the current first public UDP port as a source UDP port associated with the first user device.

Based at least in part on determining the current first public UDP IP address and/or the current first public UDP port, the MSP control infrastructure 104 may transmit, and the first client application may receive, a response indicating the current first public UDP IP address and/or the current first public UDP port associated with the first user device. Additionally, the MSP control infrastructure 104 may transmit, and the second client application may receive, second communication information indicating the current first public UDP IP address and/or the current first public UDP port associated with the first user device. As a result, the second client application may be enabled to utilize the current first public UDP IP address and/or the current first public UDP port to continue to communicate with the first user device via the meshnet connection between the first user device and the second user device.

In some aspects, the response transmitted by the MSP control infrastructure 104 may be received by the NAT device associated with the first user device at the current first public UDP port (e.g., first public port or second public port). Because the binding request was transmitted utilizing the dedicated meshnet local port and/or based at least in part on the mapping of the dedicated meshnet local port with the current first public UDP port, the NAT device may route the response back to the dedicated meshnet local port. Further, because the binding request was transmitted utilizing the dedicated meshnet local port and/or because the response from the MSP control infrastructure 104 was routed to the dedicated meshnet local port, the NAT device may continue routing all meshnet data communicated with respect to the first user device to the dedicated meshnet local port. In an example, the NAT device may route meshnet data received from the other endpoints to the dedicated meshnet local port.

The operating system associated with the first user device may accept such meshnet data received at the other local port because the operating system expects to receive meshnet data at the dedicated meshnet local port that is dedicated for communicating meshnet data. As a result, the first client application may receive the communicated meshnet data, and communication among the endpoints and the first user device may continue uninterrupted.

With respect to the second user device, the second client application and the MSP control infrastructure 104 may communicate with each other to set up a second support meshnet connection (e.g., an encrypted tunnel) for communicating encrypted data. To set up the second support meshnet connection, the second client application may utilize the MSP access information (e.g., infrastructure UDP IP address and/or infrastructure UDP port) to communicate with the MSP control infrastructure 104. In some aspects, the second client application and the MSP control infrastructure 104 may communicate to negotiate parameters (e.g., a symmetric encryption/decryption key) associated with the second support meshnet connection. In some aspects, the parameters may be randomly generated to provide optimized security to the communications. In an example, the second client application and the MSP control infrastructure 104 may negotiate a second randomly generated symmetric key that is to be utilized by the second client application and the MSP control infrastructure 104 for encrypting and decrypting data communicated via the second support meshnet connection. In some aspects, the randomly generated symmetric key may be determined based at least in part on utilizing the second assigned public key and/or a randomly generated number. Additionally, the second client application and the MSP control infrastructure 104 may utilize a secure protocol (e.g., Wireguard, IP sec, etc.) to communicate the data via the second support meshnet connection. Based at least in part on setting up the second support meshnet connection, the second client application and the MSP control infrastructure 104 may communicate encrypted data via the second support meshnet connection based at least in part on utilizing the negotiated parameters and the secure protocol.

In some aspects, the second support meshnet connection between the second user device and the MSP control infrastructure 104 may be dedicated for communicating current binding requests and associated responses. In some aspects, during operation within the mesh network (e.g., while communicating with the endpoints in the mesh network), the second client application may utilize the second support meshnet connection to transmit, to the MSP control infrastructure 104, a second current binding request to request the MSP control infrastructure 104 to determine a current second public UDP IP address (e.g., public communication address currently allocated by a NAT device associated with the second user device) and/or a current second public UDP port (e.g., public communication port currently allocated by the NAT device associated with the second user device) associated with the second user device. Because the current binding request is transmitted via the second support meshnet connection, the second client application and/or an operating system associated with the second user device may consider the current binding request as meshnet data. As a result, the second client application may utilize a second dedicated meshnet local port to transmit the binding request. Based at least in part on a mapping of the second dedicated meshnet local port with the current second public UDP port, the NAT device associated with the second user device may receive the binding request at the current second public UDP port (e.g., first public port or second public port) and may transmit the binding request to the MSP control infrastructure 104.

Based at least in part on receiving the second current binding request, the MSP control infrastructure 104 may determine the current second public UDP IP address and/or the current second public UDP port associated with the second user device. In some aspects, the MSP control infrastructure 104 may determine the current second public UDP IP address and/or the current second public UDP port based at least in part on analyzing the UDP communication (e.g., UDP IP packet) including the second current binding request received from the second user device. The UDP communication may include, for example, a header that indicates the current second public UDP IP address as a source UDP IP address and/or the current second public UDP port as a source UDP port associated with the second user device.

Based at least in part on determining the current second public UDP IP address and/or the current second public UDP port, the MSP control infrastructure 104 may transmit, to the second user device, a response indicating the current second public UDP IP address and/or the current second public UDP port associated with the second user device. Additionally, the MSP control infrastructure 104 may transmit, and the first client application may receive, first communication information indicating the current second public UDP IP address and/or the current second public UDP port associated with the second user device. As a result, the first client application may be enabled to utilize the current second public UDP IP address and/or the current second public UDP port to continue to communicate with the second user device via the meshnet connection between the first user device and the second user device.

In some aspects, the response transmitted by the MSP control infrastructure 104 may be received by the NAT device associated with the second user device at the current second public UDP port (e.g., first public port or second public port). Because the binding request was transmitted utilizing the second dedicated meshnet local port and/or based at least in part on the mapping of the second dedicated meshnet local port with the current second public UDP port, the NAT device may route the response back to the second dedicated meshnet local port. Further, because the binding request was transmitted utilizing the second dedicated meshnet local port and/or because the response from the MSP control infrastructure 104 was routed to the second dedicated meshnet local port, the NAT device may continue routing all meshnet data communicated with respect to the second user device to the second dedicated meshnet local port. In an example, the NAT device may route meshnet data received from the other endpoints to the second dedicated meshnet local port.

The operating system associated with the second user device may accept such meshnet data received at the other local port because the operating system expects to receive meshnet data at the second dedicated meshnet local port that is dedicated for communicating meshnet data. As a result, the second client application may receive the communicated meshnet data, and communication among the endpoints and the second user device may continue uninterrupted.

In some aspects, the first client application may periodically transmit the first current binding request and/or the second client application may periodically transmit the second turn binding request to the MSP control infrastructure 104. Instances associated with periodically transmitting the first current binding request and/or the second current binding request may include, for example, every 15 seconds, every 25 seconds, every 45 seconds, every 45 seconds, every 60 seconds, every 120 seconds, etc.

Further, in some aspects, the first client application may refrain from transmitting, at a given instance, the first current binding request based at least in part on determining that a condition associated with transmitting the first current binding request is satisfied. In an example, the condition may be satisfied when the first client application determines that the first client application is actively communicating data with the second client application (or another respective client application associated with another user device in the mesh network) during the given instance (e.g., at a time associated with occurrence of the given instance). In another example, the condition may be satisfied when the first client application determines that the first client application does not anticipate communicating data with the second client application (or another respective client application associated with another user device in the mesh network) for a given interval of time, and that the given instance is to occur within the given interval of time.

Similarly, the second client application may refrain from transmitting, at a given instance, the second current binding request based at least in part on determining that a condition associated with transmitting the second current binding request is satisfied. In an example, the condition may be satisfied when the second client application determines that the second client application is actively communicating data with the first client application (or another respective client application associated with another user device in the mesh network) during the given instance (e.g., at a time associated with occurrence of the given instance). In another example, the condition may be satisfied when the second client application determines that the second client application does not anticipate communicating data with the first client application (or another respective client application associated with another user device in the mesh network) for a given interval of time, and that the given instance is to occur within the given interval of time.

In a similar and/or analogous manner as discussed above with the first user device and/or the second user device, other endpoints in the mesh network may enable efficient routing of communications in the mesh network. For instance, the other endpoints in the mesh network may set up respective meshnet connections and may enable efficient routing of communications in the mesh network, as discussed herein. Additional user devices that enter the mesh network may also set up respective meshnet connections with the other user devices included in the mesh network and may enable efficient routing of communications in the mesh network, as discussed herein.

In this way, by utilizing the systems and techniques discussed herein, the MSP control infrastructure 104 and the respective client applications may enable the user devices included in the mesh network to continue to communicate with each other without interruption and mitigate instances of inefficient transmissions and retransmissions of communications among the user devices. As a result, the MSP control infrastructure and the respective client applications may enable efficient utilization of user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) for performing suitable tasks associated with the secure mesh network.

As indicated above, FIG. 4 is provided as an example. Other examples may differ from what is described with regard to FIG. 4 .

In some aspects, the process 500 may be performed by a memory and/or a processor/controller (e.g., processing unit 116, processor 820) associated with and endpoint/user device (e.g., user device 102). As shown by reference numeral 510, process 500 may include communicating, by a first device in communication with a second device in a mesh network, meshnet data with the second device based at least in part on utilizing a meshnet local port dedicated for communicating the meshnet data.
